    Hi all.

    First post.

    I inherited a 901DB from my father several years ago & im finally getting around to setting it up.

    P1110473.JPG P1110474.JPG
    I have a pair of beat up KL-88S to play with for now.

    Ive been reading threads about cleaning and all and was wondering if this should be treated similarly to changing the oil in your car i.e. something everyone should now how to do, or is it better left to professionals?

    Can someone give a suggestion for an antenna?

    Also, being as this is my first experience with vintage audio equipment, can anyone give some do/donts?
    (just read about not plugging full strength signals into the phono jacks about 12 hrs after i did it at low volume)

    Thanks!

    There is quite a bit of disassembly required to clean the controls. Would be a good idea to have the amp adjusted to spec or at least checked.

    Very nice receiver you have there. Welcome to AK.

    Here is a G-9000 I was cleaning the controls on.

    I am fairly mechanically competent. would certainly run away from a soldering iron.

    OK. I spent the weekend listening to this receiver.

    Spun some vinyl on my dopey little portable record player ( one thing at a time ) and even rigged an antenna to catch some FM.

    Ive been reading AK articles and watching YT videos on the cleaning and have convinced my self to do it.

    I will be ordering some deoxit this week, is F5 the correct/only product to get? Is there anything else i need? I saw one video where the guy was spraying canned air in after the cleaner. Is this necessary or beneficial at all? If so, is there a certain canned air i should be using?

    One other question i have is how much care should be put into avoiding over spray with the deoxit? Can that cause any issues else where?

    Thanks,

    The swiss army knife of Deoxit is D5. Use it to clean pots and switches F-5 is more of a lubricant than a cleaner. Use it as a follow up in the pots after cleaning with D-5. As far as switches, I typically start with a good quality electrical contact cleaner followed by the D-5 or G-5.

    Pete,

    I added my serial to the list.

    I ordered D5 and F5 so i guess i have that all covered.

    I read a few posts about the thinning agent in the D5 possibly being an issue but other posts saying not so much, is this an issue to worry about?

    Im working my way through the Arkay sticky on the process.

    One other thing, i imagine the AC outlets on the back are generally used for powering components and the the switched outlet is controlled by the main on/off of the unit and the other two are always hot?

    Other than the noted wattage limits are there any other concerns with using these?

    Thanks,

    Scott
